The north of the Dragon Empire, where the ancient empire first rose.
Back then, the Dragon Soul Emperor had led the brave Northern Cavalry and Knights of the Ebon Blade all the way south through the snowstorm on Coldwind Ridge, conquering the kingdoms along the way and finally achieving the great feat of ruling half the planet. From that day on, the bravery of the northern warriors became one of the most distinctive features of the country, along with the Knights of the Ebon Blade.
To this day, "fight like a Northerner" was still a phrase most often used there to praise soldiers.
